A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.

The remote RockyLinux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2024:9128 advisory.

    * libvirt: Crash of virtinterfaced via virConnectListInterfaces() (CVE-2024-8235)

Tenable has extracted the preceding description block directly from the RockyLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
